Fluoborates. Part I. Physico-Chemical Studies on the Formation of Fluoborates

From conductometric and thermometric titrations of the systems, H3BO3 -KF, H3BO3 -HF and KBO2 .H2O-HF, the existence of BF(OH)-3 , BF3(OH)- and BF-4 ions have been shown. The existence of KBF(OH)3 has been proved through the phase rule study of the system KF-H3BO3-H2O
